Rybolovlev is in the latter category, thanks to last year’s stratospheric divorce from his ex-wife, Elena, which ended with what is widely regarded as one of the most expensive settlements ever. Although a Swiss judge reduced the payout from the original $4.8 billion to $604 million, the actual settlement terms were never disclosed.

Dmitry Rybolovlev is perhaps best known in Palm Beach for having paid Donald Trump $95 million in 2008 for an oceanfront mansion at 515 N. County Road. It was the most expensive single residential sale ever on the island. But the Rybolovlevs reportedly never lived there — and in March, the property was approved for demolition. The town issued six permits for that work last week.

Trump had paid $41 million for the estate at a bankruptcy auction, 12 years before he became this year’s Republican presidential nominee.

Billionaire Dmitry Rybolovlev has reportedly never lived in his Palm Beach mansion.

Earlier this year, when the Rybolovlev divorce was mentioned in coverage of the leaked “Panama Papers” and their disclosure of secretive offshore financial vehicles, a spokeswoman for the family released a statement that said the ex-spouses had “amicably settled their matrimonial dispute.”

Dmitry Rybolovlev, who made his money in the fertilizer business, trailed only billionaire banker Mikhail Fridman, 52, on the Russian big-bucks bachelors list. Also divorced, Fridman is today worth $13.3 billion, according to Forbes.
